We discussed that on #debian-systemd, and it's likely that this is because of the change that was committed in [1]: "logind is now a lot more aggressive when suspending the machine due to a closed laptop lid. Instead of acting only on the lid close action, it will continuously watch the lid status and act on it." We suspect, that either your laptop reports an incorrect lid state or the heuristic to determine the lid state is not correct. I extracted the lid state switch into a small test program. Can you compile the attach test program (make switch). I hard-coded the lid switch button to /dev/input/input1. You'll need to change that if that's different on your system (check with evtest). You need to run that binary as root. What do you get if your that program when your lid is closed/opened? It should return 0 if the lid is open and 1 if closed.
